Sorry, gnome-system-log is still crashing (tried gnome-utils-2.13.91-1 and
gnome-utils-2.13.91-2). Furthermore, I'm no more getting an output on the
console. The annoying thing is that even with debuginfo packages installed
(actual attr-debuginfo-2.4.28-1, glib2-debuginfo-2.9.5-1,
glibc-debuginfo-2.3.90-36, gnome-utils-debuginfo-2.13.91-2,
libselinux-debuginfo-1.29.6-1 and libsepol-debuginfo-1.11.12-1), I can't get a
stacktrace (I followed the directions in the Fedora Wiki page). What's missing
so that I can produce a stracktrace in order to help solve the problem?

FYI, there's another crasher filed in bug 179688.
To get a backtrace with gdb run 'gdb /usr/sbin/gnome-system-log' as root.
Otherwise the consolehelper stuff gets in your way.
This particular bug should be fixed. Better to open a new one or comment on bug
179688, if that's your current problem.

Thanks for your report on bug 179688. I don't know if bug 179688 is related to
this one: indeed, comment #5 of bug 179688 states that gnome-utils-2.13.91-2 is
fine, which isn't the case here. I've installed the debuginfo packages listed in
my previous post (comment #3) and ran gdb gnome-system-log as root or as a user.
Unfortunately, bt pretends there's no stack and thread apply all bt has no
output at all. I'm probably missing a debuginfo package, but which one? In order
to determine which debuginfo package install, I've run ldd
/usr/bin/gnome-system-log. Only when I have a stacktrace, I may be able to check
whether this bug is similar/related to 179688 or not.

Debuginfo packages won't help in that case. They only make the backtrace more
informative. But first there must be a backtrace available at all. A backtrace
without debuginfo packages looks like bug 133969 comment #1 for instance.
In your case the program seems to exit "normally". Or you forgot to start the
program with "run" inside gdb before doing a "bt", but I doubt that...

Here's my mistake: running gdb gnome-system-log as root ends up with no stack
but a dialog box telling me that gnome-system-log quits unexpectedly. However,
running gdb /usr/sbin/gnome-system-log made the difference: the dialog box isn't
displayed but at least I can get a backtrace that seems to be different from the
one in bug 179688:

This is with up-to-date packages (attr-2.4.28-1, glib2-2.9.5-1, glibc-2.3.90-36,
gnome-utils-2.13.91-2, libselinux-1.29.6-1, libsepol-1.11.12-1), just before
"the massive rebuilt" was announced and I was advised to wait until all packages
have been rebuilt before upgrading my system to the latest packages.

gnome-system-log (from gnome-utils-2.14.0-3) is still crashing. It seems there's
something wrong with glib2 (this is with glib2-2.10.1-1). The relevant callstack
is provided in attachment 127201[details].
